BOOKMARK Filed Deo. 25, 1932 Patented July 25,` 1933 r UNITED s'm'rissv FREDERICK F. WLKOP, OF WELLESLEY, MASSACHUSETTS BOOKMARK Application filed December 23, 1932. Serial No. 648,655.

My invention relates to improvements in book marks, and the purposes and objects of this invention are to provide a book mark which will be exceedingly inexpensive to manufacture and which will lend itself readily to advertising purposes.` The material of which the mark is composed nis preferably heavy paper or thin pasteboard, although Celluloid or other thin material which readily lends itself to printed matter may also be used.

My invention is describedin the drawing accompanying this petition, in which Figure 1 is the perspective of an open book with the book mark in position, Figure 2 a plan of the book mark itself, approximately of natural size, Figure 3 is a detail sectionalA view of the book in open position with a marker therein; and Figure 4 is a detail sectional View similar to Figure 3 with the book in closed position.

In the book mark as shown in Figure 2,

A represents a longitudinal strip of pasteboard or similar material having at the upper extremity thereof a lug or projecting member E, the lower edge of which forms a right angle with the adjacent longitudinal side of the strip A.

The back of the mark, M, may be plain or may be figured in any fanciful design, and the at sides of the longitudinal member A, and projecting member E, may be used for printed matter of any kind, either in the way of mottoes or for advertising` purposes.

In Figure-1 the book mark is shown in the open book, the book being represented by the letters P-P. In Figure 1, B indicates the binding of the book, and G indicates the usual lining for holding the leaves at their inner edges.

The projecting member E at one endV of the strip A is cut away at its outer lower corner edge as at H for clearing the binding B when the book is closed with a mark therein. The book as shown in Figure 3 in open position has the lining G moved .inwardly of the binding B Land when in this position, the mark is inserted therein with the lower edge of the projection E extendingV book dealers, thus filling a popular want to 'J over the adjacent edge of the lining (fr. When the book is closed as shown in Figure 4, the lining Gr assumes its normal position relative to the back or binding B, carrying y l therewith the mark A, the cut away portion J H of the projection E clearing the adjacent edge of the back or binding so that the mark remains in its initially set position, securely held between the pages and against nr, accidental displacement. The mark is thus WL retained in this position by the lining, and the projection E `is of a length as not to project beyond the back of the book. f

Another advantage of my invention is ,V that a number of these book marks may be "9 used in the same book at the same time. It often happens-that attorneys in court and public speakers make frequent quotations from the same volume. Many forms of F book marks now in use are of such a character that only one can be used at a time in a book, but with my invention any number of marks may be used in the same volume at the same time; AS my form of book mark may be stamped Y A in enormous quantities from ordinary pasteboard or similar material, it will be seen that the price will be so trifling as to permit of free distribution by publishers and readers in all classes.

Other advantages of my mark are that it has no tendency to mar the binding or tear the leaves` of a book; and that the book may be opened without displacing the mark because the overhang E holds the mark firmly in place by its engagement with the inner lining of the back of the book.

Having now described my invention, what h d I claim and desire to secure by Letters Patent is:

1. A book mark comprised of a longitudinal member adapted to fit the angle between the leavesrof an open book, and havu ing at one extremity a projecting member, the lower edge of which projecting member is at right angles with the adjacent edge of the longitudinal member, said projecting member being adapted to engage the upper edge of the inner lining of the back of the v book and cutaway at its, lower outer edge' to clear the book backing@ thus servingA to secure the mark Within the book, whether'` thebook be opened or closed. f

2. A book mark comprising a narrow Strip jacent edge ofthe strip, the loweredge of p theprojection being adaptedto bendis'posedz 1' over tbeedge of a book lining and the forward lower-edge of the projection being cut awayto provide a recess to receive the book .v backing `when the mark ismoved by the book pages and lining in a direction toward the back'of the book during closing movement of the book lwith the mark remaining immovable relative to the lining and pages of tlieloook.4 Y Y FREDERICK WULKOP.
